Boris Souvarine (1895-1984) was one of the founders of the French Communist party (1920) and member of the Executive Committee of the Comintern (1921-1924). He gradually developed a critical view on the athmosphere of terror in the Soviet Union in the 1930s and published his main work, “Stalin”, in 1935.
